Thank you Leane for your advise. I am a very new user with Endnote. Now the problem is being solved.
I met with one of my colleagues named Sandrine " lovely and intelligent lady", and she showed me what Leane was talking about.
So thank you for both of you,
I will attach 2 pictures to demonstrate that for any Endnote user.
click endnote in word office.
click configure Bibliography.
Then change ( ) or { } to something you do not have similar parenthesis in your word office.
In my case I changed them to \ //.
See the attached picture for demonstration.
Best,
Prof T
